Make "Duration" an option configured by managers / testers

Another suggestion, the need / purpose of the duration field when running tests is clearly useful and interesting to elaborate metrics on execution time of a test campaign. Unfortunately, it might sometimes be considered as a metric to evaluate the performance or abilities of testers.

What do you think of keeping this feature by default, but also give the opportunity to the manager or tester to enable / disable the duration / timer during the execution of tests ?
